Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623824, here are decompositions:

17 + 8623807 = 8623824
23 + 8623801 = 8623824
31 + 8623793 = 8623824
37 + 8623787 = 8623824
61 + 8623763 = 8623824
67 + 8623757 = 8623824
73 + 8623751 = 8623824
103 + 8623721 = 8623824

Showing the first eight; more decompositions exist.
